This library allows a tool provider (your app) to receive LTI launches from a tool consumer (i.e. LMS). It validates LTI launches and lets an application interact with services like the Names Roles Provisioning Service (to fetch a roster for an LMS course) and Assignment Grades Service (to update grades for students in a course in the LMS). This library was forked from [IMSGlobal/lti-1-3-php-library](https://github.com/IMSGlobal/lti-1-3-php-library), initially created by @MartinLenord. [Packback](https://packback.co) found the library immensely helpful and extended it over the years. It has been rewritten by Packback to bring it into compliance with the standards set out by the PHP-FIG and the IMS LTI 1.3 Certification process. Packback actively uses and maintains this library. Installation ------------ [](#installation) Run: ``` composer require packbackbooks/lti-1p3-tool ``` In your code, you will now be able to use classes in the `Packback\Lti1p3` namespace to access the library. ### Configure JWT [](#configure-jwt) Add the following when bootstrapping your app. ``` Firebase\JWT\JWT::$leeway = 5; ``` ### Implement Data Storage Interfaces [](#implement-data-storage-interfaces) This library uses three methods for storing and accessing data: cache, cookie, and database. All three must be implemented in order for the library to work. You may create your own custom implementations so long as they adhere to the following interfaces: - `Packback\Lti1p3\Interfaces\ICache` - `Packback\Lti1p3\Interfaces\ICookie` - `Packback\Lti1p3\Interfaces\IDatabase` or optionally `Packback\Lti1p3\Interfaces\IMigrationDatabase` View the [Laravel Implementation Guide](https://github.com/packbackbooks/lti-1-3-php-library/wiki/Laravel-Implementation-Guide) to see examples (or copy/paste the code outright). ### Create a JWKS endpoint [](#create-a-jwks-endpoint) A JWKS (JSON Web Key Set) endpoint can be generated for either an individual registration or from an array of `KID`s and private keys. ``` use Packback\Lti1p3\JwksEndpoint; // From issuer JwksEndpoint::fromIssuer($database, 'http://example.com')->getPublicJwks(); // From registration JwksEndpoint::fromRegistration($registration)->getPublicJwks(); // From array JwksEndpoint::new(['a_unique_KID' => file_get_contents('/path/to/private/key.pem')])->getPublicJwks(); ``` Documentation ------------- [](#documentation) [The wiki](https://github.com/packbackbooks/lti-1-3-php-library/wiki) provides more detailed information about how to use this library, including a [Laravel Implementation Guide](https://github.com/packbackbooks/lti-1-3-php-library/wiki/Laravel-Implementation-Guide). Contributing ------------ [](#contributing) For improvements, suggestions or bug fixes, make a pull request or an issue. Before opening a pull request, add automated tests for your changes, ensure that all tests pass, and any linting errors are fixed. ### Testing [](#testing) Automated tests can be run using the command: ``` composer test ``` Linting can be run using ``` # Display linting errors composer lint # Automatically fix linting errors composer lint-fix ``` ### Health Score 39 — LowBetter than 86% of packages Maintenance83 Actively maintained with recent releases Popularity8 Limited adoption so far Community19 Small or concentrated contributor base Maturity42 Maturing project, gaining track record Bus Factor1 Top contributor holds 64.6% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
